It has been a century since three “isms” were promoted, that undermined the United States!
We had the rise of Isolationism in the 1920s and 1930s, after World War I, a very powerful movement, particularly among Republicans, which became a major challenge for Franklin D. Roosevelt and the New Deal.
This author and blogger wrote about this in his first book–TWILIGHT OF PROGRESSIVISM: THE WESTERN REPUBLICAN SENATORS AND THE NEW DEAL (Johns Hopkins University Press, 1981).
We also saw the rise of Protectionism, the idea of high protective tariffs, which was pursued by Republican Presidents Warren G. Harding, Calvin Coolidge, and Herbert Hoover.
Hoover, in particular, pursued this with the Hawley Smoot Tariff of 1930, which made the emerging Great Depression only multipled in 1930 and after, and this despite hundreds of economists taking out newspaper ads, appealing to Hoover to reject higher tariffs.
And we also had nativism, with the passage of extremely restrictive immigration laws in the 1920s under Calvin Coolidge, discriminating against Catholic, Jewish, and Asian immigrants, an apology that led to great human tragedy during the 1930s and World War II.
Now, we have Donald Trump and the Republican Party pursuing the goal of Isolationism (unwillingness to back Ukraine in its war with Russia, weakened support of the North Atlantic Treaty Organization (NATO), and expressing doubts about supporting the sovereignty of Taiwan against mainland China)!
And we have Protectionism rearing its ugly head, with Trump promoting the idea of 10 percent tariffs on all foreign goods, which will raise the prices to American consumers, causing major rises in the cost of living!
Finally, we have Nativism, with the pledge of Trump to deport up to 11 million migrants, both undocumented immigrants and others who are not citizens of the United States, bringing back memories of detention camps promoted by Trump in his first term, including separation of children from their parents!
America cannot allow these old “isms” to become government policy again, as we need to learn from mistakes of a century ago!
